In the assumptions regarding to the transport policy both at the level of country and Europe there is the concept of sustainable development of transport. Warsaw University of Technology in cooperation with Poznan University of Technology performs research work concerning the shaping of environmentally friendly transport system – Project EMITRANSYS. In this project, one of the conditions is to reduce exhaust emissions by means of transport. The paper presents the reasons for the testing of the exhaust emissions under Real Driving Emissions testing (RDE). Research potential of Institute of Combustion Engines and Transport at Poznan University of Technology in the area of road testing of passenger and heavy-duty vehicles has been presented in the paper. Example test results have been shown in the aspect of the emission-related classification of vehicles.

The paper presents a comparative analysis of the emission of CO, NOx, CO2 and gas mileage for two heavy-duty long haulage vehicles. The tests were performed on the same test road. The test route reflected typical daily operation of heavy-duty vehicles – a drive to the loading/unloading zone and cruise on national roads. In the investigations, the authors used a portable exhaust emissions analyzer (SEMTECH DS, PEMS – Portable Emissions Measurement System). Based on the performed analysis, optimum engine was selected for long haulage vehicles under conditions of Polish transport and logistic infrastructure in terms of fuel consumption.

Heavy Duty Vehicles

An experimental and theoretical investigation is being performed with a view to evaluate the contribution of Heavy duty vehicles (HDVs) to exhaust emissions and fuel consumption in urban areas involved by commercial shipping activities. Reference is made to the city of Genoa, whose urban road network is influenced both by shipping activities and highway connections, as more than twenty accesses to port area and seven motorway exits are available within the urban area. Different aspects were deepened in this study. Firstly, the HDV flows crossing highway exits, urban zones and port areas were assessed, as well as the relevant vehicle classes. Secondly, the typical urban trips linking highway exits to port gates and the HDV mission profiles within the port area were identified. Measurements of HDV instantaneous speed related to the urban trips were then planned aiming at the definition of the most representative speed patterns through a proper statistical data processing, enabling the application of Passenger Car and Heavy Duty Emission Model (PHEM) for the estimation of emission and fuel consumption factors for selected HDV classes. The main results of the different investigation steps are presented and discussed in the paper, outlining the peculiar mission of HDVs in port area and the related emissive behavior.
